Imap email can't connect

I get 'The connection to the server IMAP Account was unexpectedly closed or timed out. It will be re-established automatically if possible.' from kmail. It had been running fine for about 6/7 hours checking every 10mins and nothing was changed. The portal just throws me back to the login page with the error message 'Username/Password match not found, please try again.'

I can still access all my emails in my inbox that were sent up until yesterday (using webmail and pop3 on my Force9 account). But there has been nothing new in there since yesterday and as they get spammed everyday that does seem strange.

Can log in now and retrieve mail. However I definitely have mail outstanding, some sent as long as 12hrs ago. Is this going to be another week of seriously delayed mail? Can someone from Plusnet let me know if this will be fixed today or should I look at moving my email account (and then prehaps my ISP) to a more reliable one.
